The other obvious promotion from within is Dave McGinnis, who used to be the HC of the Arizona Cardinals. He's our Assistant HC/LB Coach.
Gregg Williams is another failed HC who used to be a Titans assistant. The man knows how to run a defense, though.
Then there are the dream guys, like Cowher and Gruden.
Russ Grimm is a thought too, and The Leaf Chronicle brought up Reinfeldt's Seattle connection with Mike Holmgren, so it stands to reason that he'll look into guys who are from the Holgren coaching tree. Plus, we'll probably interview Perry Fewell.
